Tilt Analyzer
Measure the uniform slope between the two ends of a profile — the endpoint-to-endpoint tilt, updated live as you type.
Inputs
Horizontal (ft)
Elevation (in)
P₁
P₃
Tilt uses only the two end points — P₁ is the start (fixed at 0) and P₃ is the end. Because tilt is a slope (rise ÷ run), units matter: elevations in inches and length in feet give a result in in/ft.
Formula
Tilt=Y3−Y1L
Negative = downward slope (end lower than start) · Positive = upward slope

| Allowable tilt (L / 360 basis) | 0.0333 in/ft |
| Status | — |
Allowable tilt is the uniform slope whose end-to-end drop equals L / 360 (≈ 0.0333 in/ft). The document defines L/360 for deflection, not tilt — adjust the ratio or ask to use a different tilt standard.
